Head smut is a soil-borne systemic disease in maize caused by fungus Sporisorium reilianum,and poses a grave threat to global maize production.Previous studies detected a major resistance QTL qHSR1 on maize chromosome bin2.09,which could reduce the disease incidence by 25％.With a recombinant-derived progeny test method,we narrowed down the qHSR1 region to an interval flanked by the markers STS1M3 and STS3M1.The positive BAC clones on the qHSR1 region were obtained from both the resistant Mo 17 and susceptible HZ4 BAC libraries,and subjected to sequencing.

茄子喜温不耐寒。项目组前期已克隆了拟南芥冷调控转录因子AtCBF3基因，利用冷诱导基因启动子RD29A构建高效表达载体，采用农杆菌介导的方法，将抗寒基因AtCBF3导入茄子基因组，获得了茄子转基因植株。对这些转化后代进行抗寒性与分子检测研究，以验证AtCBF3基因对茄子抗寒性的影响及AtCBF3基因在茄子上的表达。
厚皮甜瓜在海南高温高湿条件下贮藏易发生果皮长斑、果肉软化和果腐病等，导致采后供应期短。本研究中探索了贝壳粉溶液、不同温度和包装材料处理对厚皮甜瓜采后生理及贮藏品质的影响。
辣椒素具有重要的生物活性，只在辣椒属植物中合成和积累。分析表明：辣椒素在辣椒果实胎座和隔膜上的腺体细胞中合成，然后通过子房隔膜运输到果肉表皮细胞，并在液泡中积累。因此在辣椒果实的各组织中，胎座和隔膜组织辣椒素含量最高，种子最低，果肉居中。
本研究旨在建立一套适合辣椒同型不育系和同型保持系幼苗时期蛋白质组学分析的电泳体系,为进一步探讨辣椒雄性不育机制奠定基础.取1 g苗龄为50 d的辣椒幼苗(此时植株有8～10片真叶),用超纯水冲洗干净,加入0.1g丙酮溶液Ⅰ(含10％三氯乙酸TCA、0.07％β-巯基乙醇、89.93％丙酮),液氮冰浴研磨至细粉状,转入离心管,-20℃静置1h,于4℃、20 000×g下离心30 min,弃上清液；加
亚洲莲(Nelumbo nucifera Gaertn.)品种繁多，花器官变异极其丰富，是研究花器官发育分子机制的良好材料.调控花发育的基因很多，其中MADS-box基因是花器官发育过程的主要调控基因.SEPA LLA TA(SEP)基因属于MADS-box E类基因，是花器官发育所必需的，对于花分生组织以及花器官的形成不可或缺.为了研究SEP3基因在莲花器官发育的分子机理，以亚洲莲重瓣花品种大洒
Most tropical mammal species are threatened or data-deficient but data collection is impeded by monitoring approaches which can be laborious,expensive and struggle to detect cryptic diversity.

As one of biodiversity hotspots,southwest China is also highly rich in fungi,including boletes.Moreover,boletes are ecologically and economically very important,especially in southwest China.However,d
Seed dispersal is vital for plant in their life cycle.The majority of plants rely on vertebrate frugivores to disperse their seeds by offering a reward for swallowing them in the form of fruit.The fru
The genus Ilex in the phylogenetically isolated monogeneric family Aquifoliaceae is the largest woody dioecious clade,with around 700 species.Geographical distribution of Ilex is strongly constrained
